Answer» Given:- FORCE(F)=5N Case1:- Mass=m1 Acceleration(A1)=10m/s² Case 2:- Mass=m2 Acceleration(a2)=20m/s² To find:- Acceleration of the BODY for mass m1+m2 Solution:- Here,we shall be using Newton's second law of motion i.e.---- F=ma m1=F/a1 m1=5/10 m1=1/2kg m2=F/a2 m2=5/20 m2=1/4kg Thus,M=m1+m2 M=1/2+1/4 M=3/4kg Now,a=F/M a=5/3/4 a=20/3m/s² Thus,acceleration when both the MASSES are tied together is 20/3m/s².

Answer»

Given:-

FORCE(F)=5N

Case1:-

Mass=m1

Acceleration(A1)=10m/s²

Case 2:-

Mass=m2

Acceleration(a2)=20m/s²

To find:-

Acceleration of the BODY for mass m1+m2

Solution:-

Here,we shall be using Newton's second law of motion i.e.----

F=ma

m1=F/a1

m1=5/10

m1=1/2kg

m2=F/a2

m2=5/20

m2=1/4kg

Thus,M=m1+m2

M=1/2+1/4

M=3/4kg

Now,a=F/M

a=5/3/4

a=20/3m/s²

Thus,acceleration when both the MASSES are tied together is 20/3m/s².
